(for Electrical Connections).

A. UNPACKING / SETTING UP

Remove protective shipping material (i.e., plastic wrap and/or optional shipping box) from dryer.

NOTE: The access keys for the service doors are included in the information packet shipped in the

basket (tumbler). These keys should be removed and put in a safe place, yet made

accessible because they will be needed throughout various phases in the installation of the

dryer.

Dryers are shipped with a coin box and coin box faceplate ONLY. The coin box lock is not included and

must be purchased elsewhere or the lock can be ordered as a parts order from the ADC Parts Department at

(508) 678-9000.

The dryer can be moved to its final location while still attached to the skid or with the skid removed. To unskid

the dryer, locate and remove the four (4) bolts securing the base of the dryer to the wooden skid. Two (2) are

at the rear of the base and two (2) are located in the front. Once the bolts are removed, slide the dryer off of the

skid.

With the skid removed, to make it easier to slide the dryer into its final position, slightly lower ALL the leveling

legs so that the dryer will slide on the legs instead of the base frame. The dryer is equipped with four (4) leveling

legs, one (1) at each corner of the dryer base.

8 American Dryer Corp. 113215- 12

B. LOCATION REQUIREMENTS

Before installing the dryer, be sure the location conforms to local codes and ordinances. In the absence of such

codes or ordinances the location must conform with the National Fuel Gas Code ANSI.Z223.1 LATEST

EDITION, or in Canada, the installation must conform to applicable Canadian Standards: CAN/CGA-B149.1-

M91 (Natural Gas) or CAN/CGA-B149.2-M91 (Liquid Propane [L.P.] Gas) or LATEST EDITION (for General

Installation and Gas Plumbing).

1. The dryer must be installed on a sound level floor capable of supporting its weight. Carpeting must be

removed from the floor area that the dryer is to rest on.

IMPORTANT: “The dryer must be installed on noncombustible floors only.”

2. The dryer must not be installed or stored in an area where it will be exposed to water and/or weather.

3. The dryer is for use in noncombustible locations.

4. Provisions for adequate air supply must be provided as noted in this manual (refer to Fresh Air Supply

Requirements in Section D).

5. Clearance provisions must be made from combustible construction as noted in this manual (refer to Dryer

Enclosure Requirements in Section C).

6. Provisions must be made for adequate clearances for servicing and for operation as noted in this manual

(refer to Dryer Enclosure Requirements in Section C).

7. The dryer must be installed with a proper exhaust duct connection to the outside as noted in this manual

(refer to Exhaust Requirements in Section E).

8. The dryer must be located in an area where correct exhaust venting can be achieved as noted in this

manual (refer to Exhaust Requirements in Section E).

IMPORTANT: The dryer should be located where a minimum amount of exhaust duct will be

necessary.

9. The dryer must be installed with adequate clearance for air openings into the combustion chamber.

CAUTION: This dryer produces combustible lint and must be exhausted to the outdoors. Every 6

months, inspect the exhaust ducting and remove any lint build up.

IMPORTANT: The dryer must be installed in a location/environment, which the ambient

temperature remains between 40° F (4.44° C) and 130° F (54.44° C).

113215- 12 www.adclaundry.com 9

C. DRYER ENCLOSURE REQUIREMENTS

Bulkheads and partitions must be made of noncombustible materials and must be located a minimum of

12-inches (30.48 cm) above the dryer outer top, except along the front of the dryer which may be partially closed

in if desired. It is suggested that the dryer be positioned about 2 feet (0.61 meters) away from the nearest

obstruction, for ease of installation, maintenance, and service (to be measured from the back guard).

NOTE: Allowances must be made for opening the control door.

Dryers may be positioned sidewall to sidewall. However, a 1/16” (1.5875 mm) minimum allowance must be

made for the opening and closing of the control door. Refer to the illustration below for details.

NOTE: Air considerations are important for proper and efficient operation.

IMPORTANT: When fire sprinkler systems are located above the dryers, a minimum of 18-inches

(45.72 cm) above the dryer console (module) is required.

10 American Dryer Corp. 113215- 12

EXAMPLE: For a bank of four (4) dryers, a total make-up air opening of 6 square feet (0.55 square meters) is

required. Two (2) unrestricted openings measuring 18-inches by 24-inches (45.72 cm by 60.96 cm) are acceptable.

Allowances must be made for remote or constricting passageways or where dryers are located at excessive

altitudes or predominantly low pressure areas.

IMPORTANT: Make-up air must be provided from a source free of dry cleaning solvent fumes.

Make-up air that is contaminated by dry cleaning solvent fumes will result in

irreparable damage to the motors and other dryer components.

NOTE: Component failure due to dry cleaning solvent fumes will VOID THE WARRANTY.

D. FRESH AIR SUPPLY REQUIREMENTS

This appliance may only be installed in a room that meets the appropriate ventilation requirements specified in

the national installation regulations.

When the dryer is operating, it draws in room air, heats it, passes this air through the basket (tumbler), and

exhausts it out of the building. Therefore, the room air must be continually replenished from the outdoors. If the

make-up air is inadequate, drying time and drying efficiency will be adversely affected. Ignition problems and

sail switch “fluttering” problems may result, as well as premature motor failure from overheating.

Air supply (make-up air) must be given careful consideration to ensure proper performance of each dryer. An

unrestricted source of 800 cfm (22.66 cmm) is necessary for each dryer. As a general rule, an unrestricted air

entrance from the outdoors (atmosphere) of a minimum of 1-1/2 square feet (0.41 square meters) is required for

each dryer. The area must be enlarged if louvers or registers cover the openings. The dryer must be installed

with provisions for adequate combustion and make-up air supply.

To compensate for the use of registers or louvers used over the openings, this make-up air must be increased by

approximately thirty-three percent (33%). Make-up air openings should not be located in an area directly near

where exhaust vents exit the building.

It

is not necessary to have a separate make-up air opening for each dryer. Common make-up air openings are

acceptable. However, they must be set up in such a manner that the make-up air is distributed equally to ALL

the dryers.

A = 18” (45.72 cm)

B = 24” (60.96 cm)

113215- 12 www.adclaundry.com 11

E. EXHAUST REQUIREMENTS

Exhaust ductwork should be designed and installed by a qualified professional. Improperly sized ductwork will

create excessive back pressure which results in slow drying, increased use of energy, overheating of the dryer,

and shut down of the burner by the airflow (sail) switches, burner hi-limits, or basket (tumbler) hi-limit thermostats.

The dryer must be installed with a proper exhaust duct connection to the outside.

The design of the flue system shall be such that any condensate formed when operating the appliance from cold

shall either be retained and subsequently re-evaporated or discharged.

CAUTION: This dryer produces combustible lint and must be exhausted to the outdoors.

CAUTION: IMPROPERLY SIZED OR INSTALLED EXHAUST DUCTWORK CAN

CREATE A POTENTIAL FIRE HAZARD.

The ductwork should be laid out in such a way that the ductwork travels as directly as possible to the outdoors

with as few turns as possible.

1. Single Dryer Venting

Where possible, it is suggested to provide a separate exhaust duct for each dryer. The exhaust ductwork

should be laid out in such a way that the ductwork travels as directly as possible to the outdoors with as

few turns as possible. It is suggested that the use of 90° turns

be avoided; use 30° and/or 45° bends

instead. The radius of the elbows should preferably be 1-1/2 times the diameter of the duct. The shape

of the ductwork is not critical as long as the minimum cross-sectional area is provided.

IMPORTANT: Exhaust back pressure measured by a manometer/magnehelic in the exhaust duct

must be no less than 0 and must not exceed 0.3 in WC (0.74 mb) with both baskets

(tumblers) operating.

NOTE: It is recommended that exhaust or booster fans not be used in the exhaust ductwork system

except where necessary to maintain exhaust back pressure (in the exhaust duct) between zero

and 0.3 inch water column with both baskets (tumblers) operating. Where employed, booster

fans must not activate the dryer airflow proving switch (sail switch) when the dryer is not in

operation.

It is suggested that the ductwork from each dryer must not exceed 20 feet (6.1 meters) with no more than

two (2) elbows. If the ductwork exceeds 20 feet (6.1 meters) or has numerous elbows, the cross-sectional

area of the ductwork must be increased in proportion to the length or number of elbows in it.

IMPORTANT: For extended ductwork runs, the cross-sectional area of the ductwork can only be

increased to an extent. When the ductwork approaches the maximum limits as noted

in this manual, a professional heating, ventilating, and air-conditioning (HVAC) firm

should be consulted for proper venting information.

NOTE: As per the National Fuel Gas Code, “Exhaust ducts for Type 2 clothes dryers shall be

constructed of sheet metal or other noncombustible material. Such ducts shall be equivalent in

strength and corrosion resistance to ducts made of galvanized sheet steel not less than

0.0195 inches (26 gauge [0.5 mm]) thick.”

12 American Dryer Corp. 113215- 12

ALL ductwork should be smooth inside with no projections from sheet metal screws or other obstructions,

which will collect lint. When adding ducts, the duct to be added should overlap the duct to which it is to be

connected.

ALL ductwork joints must be taped to prevent moisture and lint from escaping into the

building. Inspection doors should be installed at strategic points in the exhaust ductwork for periodic

inspection and cleaning of lint from the ductwork.

NOTE: When the exhaust ductwork passes through a wall, ceiling, or roof made of combustible

materials, the opening must be 2-inches (5.08 cm) larger than the duct (all the way around).

The duct must be centered within this opening.

Outside Ductwork Protection

To protect the outside end of the horizontal ductwork from the weather, a 90° elbow bent downward should

be installed where the exhaust exits the building. If the ductwork travels vertically up through the roof, it

should be protected from the weather by using a 180° turn to point the opening downward. In either case,

allow at least twice the diameter of the duct between the duct opening and the nearest obstruction.

IMPORTANT: DO NOT use screens, louvers, or caps on the outside opening of the exhaust

ductwork.

2. Multiple Dryer (Common) Venting

If it

is not feasible to provide a separate exhaust duct for each dryer, ducts from individual dryers may be

channeled into a “common main duct.” The individual ducts should enter the bottom or the side of the main

duct at an angle not more than 45° in the direction of the airflow. The main duct should be tapered with

the diameter increasing before each individual 8-inch (20.32 cm) duct is added.

IMPORTANT: No more than eight (8) dryers should be connected to one (1) main common duct

(refer to the illustration on the following page).

The main duct may be any shape as long as the minimum cross-sectional area is provided. The illustration

on the following page shows the minimum cross-sectional area for multiple dryer venting. These figures

must be increased in proportion as the result of whatever changes or additions are made to this ductwork

run. Two examples are if ductwork length from last dryer to where duct exits the building exceeds limits

noted (20 feet [6.1 meters]) or, if ductwork runs from last dryer to where duct exits the building has more

than one (1) elbow (including outside protection).

113215- 12 www.adclaundry.com 13

NOTE: Refer to the illustration below for examples of multiple dryer (common) venting.

IMPORTANT: For extended ductwork runs, the cross-sectional area of the ductwork can only be

increased to an extent. When the ductwork approaches the maximum limits as noted

in this manual, a professional heating, ventilating, and air-conditioning (HVAC) firm

should be consulted for proper venting information.

IMPORTANT: Exhaust back pressure measured by a manometer/magnehelic in the exhaust duct

must be no less than 0 and must not exceed 0.3 in WC (0.74 mb) with both baskets

(tumblers) operating.

NOTE: It is recommended that exhaust or booster fans not be used in the exhaust ductwork system

except where necessary to maintain exhaust back pressure (in the exhaust duct) between zero

and 0.3 inch water column with both baskets (tumblers) operating. Where employed, booster

fans must not activate the dryer airflow proving switch (sail switch) when the dryer is not in

operation.

The ductwork should be smooth inside with no projections from sheet metal screws or other obstructions,

which will collect lint. When adding ducts, the duct to be added should overlap the duct to which it is to be

connected. ALL ductwork joints must be taped to prevent moisture and lint from escaping into the building.

Inspection doors should be installed at strategic points in the exhaust ductwork for periodic inspection and

cleaning of lint from the ductwork.

NOTE: When the exhaust ductwork passes through a wall, ceiling, or roof made of combustible

materials, the opening must be 2-inches (5.08 cm) larger than the duct (all the way around).

The duct must be centered within this opening.

To protect the outside end of the horizontal ductwork from the weather, a 90° elbow bent downward should

be installed where the exhaust exits the building. If the exhaust ductwork travels vertically up through the

roof, it should be protected from the weather by using a 180° turn to point the opening downward. In either

case, allow at least twice the diameter of the duct between the duct opening and nearest obstruction.

F. ELECTRICAL INFORMATION

1. Electrical Requirements

ALL electrical connections must be made by a properly licensed and competent electrician. This is to

ensure that the electrical installation is adequate and conforms to local and state regulations or codes. In the

absence of such codes,

ALL electrical connections, materials, and workmanship must conform to the

applicable requirements of the National Electrical Code ANSI/NFPA NO. 70-LATEST EDITION or in

Canada, the Canadian Electrical Codes Parts 1 & 2 CSA C22.1-1990 or LATEST EDITION.

IMPORTANT: Failure to comply with these codes or ordinances, and/or the requirements

stipulated in this manual can result in personal injury or component failure.

NOTE: Component failure due to improper installation will VOID THE WARRANTY.

Each pocket should be connected to an independently protected branch circuit. The dryer must be

connected with copper wire only. DO NOT use aluminum wire, it could create a fire hazard. The

copper conductor wire/cable must be of proper ampacity and insulation in accordance with electric codes

for making ALL service connections.

NOTE: The use of aluminum wire will VOID THE WARRANTY.

IMPORTANT: A separate protected circuit must be provided to each pocket.

NOTE: An individual ground circuit must be provided to each dryer, do not daisy chain.

IMPORTANT: The dryer must be connected to the electric supply shown on the data label. In

the case of 208 VAC or 240 VAC, the supply voltage must match the electric service

specifications of the data label exactly.

IMPORTANT: The wire size must be properly sized to handle the related current.

WARNING: 208 VAC AND 240 VAC ARE NOT THE SAME. Any damage done to dryer

components due to improper voltage connections will automatically VOID THE

WARRANTY.

NOTE: Component failure due to improper voltage application will VOID THE WARRANTY.

NOTE: ADC reserves the right to make changes in specifications at any time without notice or

obligation.

3. Grounding

A ground (earth) connection must be provided and installed in accordance with state and local codes. In

the absence of these codes, grounding must conform to applicable requirements of the National Electrical

Code ANSI/NFPA NO. 70-LATEST EDITION, or in Canada, the installation must conform to applicable

Canada Standards: Canadian Electrical Codes Parts 1 & 2 CSA C22.1-1990 or LATEST EDITION. The

ground connection may be to a proven earth ground at the location service panel.

For added personal safety, when possible, it is suggested that a separate ground wire (sized per local codes)

be connected from the ground connection of the dryer to a grounded cold water pipe. DO NOT ground to

a gas pipe or hot water pipe. The grounded cold water pipe must have metal-to-metal connection ALL

the way to the electrical ground. If there are any nonmetallic interruptions, such as, a meter, pump, plastic,

rubber, or other insulating connectors, they must be jumped out with no. 4 copper wire and securely

clamped to bare metal at both ends.

IMPORTANT: For personal safety and proper operation, the dryer must be grounded.

Provisions are made for ground connection in each dryer at the electrical service connection area.

4. Electrical Connections

A wiring diagram is located inside the control box for connection data.

If local codes permit, power to the dryer can be made by the use of a flexible U.L. listed power cord/pigtail

(wire size must conform to rating of dryer), or the dryer can be hard wired directly to the service breaker

panel. In both cases, a strain relief must be installed where the wiring enters the dryer.

IMPORTANT: A separate protected circuit must be provided to each pocket.

Single-Phase (1ø) Hookup

The electrical input connections on

ALL single-phase (1ø) dryers are made into the junction box located at

the upper rear of the dryer. A separate circuit servicing each pocket must be provided.
